NOTES:

1. The cumulative program time must not be exceeded when writing to a 64-byte flash block. This parameter applies to all programming

methods: individual word/byte write and block write modes.

achieve the required cumulative mass erase time the Flash Controller’s mass erase operation can be repeated until this time is met.

(A worst case minimum of 19 cycles are required).
